Tesla Powerwall

TESLA POWERWALL is a rechargeable home battery system designed to maximize your home’s energy independence. That means seamless backup and a smaller carbon footprint for your home, and potentially savings on your electricity bill. Powerwall is an intelligent system that can be customized to your energy needs, with the ability to charge from solar so energy is always available on demand.

Seamless Backup

When the grid goes down, solar energy will continue to power your home and charge your Powerwall. With Storm Watch enabled, Powerwall can communicate to the National Weather Service and prioritize charging in anticipation of severe weather.

Self-Powered Home

At night, Powerwall can provide your home with clean energy that you’ve generated from solar during the day.

Time-Based Control

If your utility offers Time-of-Use rates, you can use less expensive solar energy you’ve already generated to avoid electrical charges during more expensive rate periods.


Each Powerwall installation includes a complete energy monitoring solution for your home. You can see how your home both produces and uses energy at any given time.

Tesla Powerwall FAQ's

What is a Tesla Powerwall?

Tesla Powerwall is a rechargeable home battery system that stores energy from solar or from the grid and makes it available on demand. With its built-in battery inverter, Powerwall is compact and easy to integrate into your home. As with all Tesla products, new features will be added to Powerwall with over-the-air updates.

How does the Tesla Powerwall store and use Solar Energy?

When solar is producing more power than the home is using, Powerwall captures and stores that energy. When the home is consuming more energy than solar is providing, Powerwall discharges enough energy to offset the home usage. If solar is producing more than Powerwall can store, or the home needs more than Powerwall can provide, the remainder is automatically exported or imported from the grid respectively.

What are the different components that make up a Powerwall system?

A Powerwall system consists of at least one Powerwall battery and a Gateway. The Gateway provides energy management, metering and monitoring functions for Powerwall. The Gateway also includes communication functions for up to 10 Powerwalls, and receives over-the-air updates for the system.

How do I download and set up the Tesla mobile app?

The Tesla app is available on the iTunes and Google Play stores. You can download the Tesla mobile app from your regular app store on your device. Log in using your Tesla account information and you will see all your Tesla products in one place.
